MEANS FOR DRIVING SLUBBING AND ROl/ING MACHINES.

SPECIFICATION forming part of Letters Patent No. 514,693, dated February13, 1894. I Application filed December 1, 1892. Serial No. 453,903. (Nomodel.) Patented in England September 28, 1 5

7 To all whom it may concern:

provements in Means for Driving Slubbing and. Roving Machines, (forwhich we have obtained Letters Patent in Great Britain, No.

12,328, bearing date September 28, 1886,) of which the following is aspecification.

The object of this invention is an improved application of cone drums tothe winding mechanism of slubbing, intermediate and roving frames, andalso to the self-feeding regulators of lap machines whereby theirregularity in driving heretofore experienced and arising from unequalgrip of the two edges of the strap upon the varying diameter of the conedrums is considerably obviated.

In performing our invention instead of mm ploying' a single pair of conedrums as heretofore we use two or more cones on the same driving anddriven shaft and a correspond ing additional number of cone strapscapable of moving simultaneously and thus we are enabled to-use narrowerstraps than heretofore and yet obtain a better grip and a more certainand reliable driving action.

On the accompanying drawings Figurel is a back View of so much of aroving frame as is necessary to. explain our improvements which areillustrated applied thereto and which'improvements are equallyapplicable to slubbing and intermediate frames. a transverse section ofFig. 1 on line wa:.

In both views a and b are the upper and lower cone shafts for impartingthe varying speed to the winding and lifting mechanisms. In accordingwith this invention each of these shafts is fitted with a pair of conesmarked respectively c. c and d. d and round which cones are passed apair of driving belts or straps c and d. It will be apparentthat as thecones on each shaft are exact facsimiles of each other it will benecessary toinsure their driving belts or straps occupying constantlythe same relative position on each set of cones and that they shall bemoved to and fro along Fig.2 isgreater length can be driven upon thisprinv ciple.

Our improvements are equally applicable to the self-feeding regulatorsof lap machines.

and consist in applying a pair of cones upon each cone shaft and M'hlGllare dI'IVOIl and operated simultaneously as hereinbefore desc'ribedthestrap levers (which are geared together by means of sector wheels in theordinary 'way) being fitted in each case with a double (instead of asingle) strap fork so as to move both driving straps simultaneouslyalong their respective cones.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination, with the shafts a. and b,

of two similar cones a secured upon the shaft a, two similar cones 61secured upon the shaft 1) under the said cones c, and two separatenarrow driving belts c and (1' connecting the respective pairs of cones,substantially as and for the purpose set forth.

2. The combination, with the shafts ct and b, of two similar cones csecured upon'the shaft a, two similar cones 01 secured on the shaft I)under the said cones a, two separate narrow driving belts c and (1'connecting the respective pairs of cones, and a belt shifting devlceoperating upon both of the said belts slmultaneously, substantially asand for the purpose set forth.

In testimony whereof we affix our signatures to the foregoingspecification.
